## Pydantic modellen

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> is een Python-pakket voor het uitvoeren van datavalidatie.

Je declareert de "vorm" van de data als klassen met attributen.

Elk attribuut heeft een type.

     * given user when the target object's ACL has local groups. Local groups
     * are not listed in a user's group membership (e.g. as represented by the
     * tokenGroups constructed attribute retrived via LDAP).
     * <p/>
     * Domain groups nested inside a local group are currently not expanded. In
     * this case the key (SID) type will be SID_TYPE_DOM_GRP rather than
     * SID_TYPE_USER.
     *

... et voyez comment votre éditeur complétera automatiquement les attributs et connaîtra leurs types :

Définir des validations supplémentaires pour les types de données utilisant la valeur "par défaut" des attributs du modèle. Ceci améliore le support de l'éditeur, et n'était pas disponible dans Pydantic auparavant.
